WordPress multisite

Hi,

I use Favorite posts on a multisite installation.
The plugin is just great, but unfortunately it’s not working properly with a network.
If you add a favorite post on a site of the network and if another post, on another site has the same ID, then they are both stored as favorite posts.
Maybe you could give me an advice to add the site ID and not only the post ID in the cookie? I don’t use the database (no login on the site).
Another solution would be to duplicate the plugin and activate it independently for each site. But cookies should be different and maybe some variables should be renamed. Any advice for that?

Thanks a lot in advance for your help.
